NETWORK VARIABLES
6.5 Inverter Basic Functions
6.5.1 Inverter input signal (network input SNVT_state nviInvInputSig)
A 16-bit-wide input signal to the inverter.
⋅ The initial value of all bits are"0".
⋅ Data acceptance timing........... At network variable receive (nv_update_occurs event)
Bit Signal Name Description
0 Forward rotation command *2
0: Stop command
1: Forward rotation start
A starting command is input to the
inverter when the signal turns to 1.
A stop command is given when both
signals turn to 1 simultaneously.
1 Reverse rotation command
*2
0: Stop command
1: Reverse rotation start
